1 power any natural number is 1
Answer:
$21.25
Step-by-step explanation:
x - x(0.20) = 17
0.8x = 17
x = 21.25
Answer:
D
Step-by-step explanation:
(the line is a / shape, so the slope is positive)
(the line crosses the y axis at (0,-2))
(using the above information, we can conclude that the equation is y=2x-2)
or
slope = m = rise/run = 2/1 = 2
y=mx+b
y=2x+b
Choose any point on the line) (1,0)
0=2(1)+b
b=-2
y=2x-2
P multiplied by 2.60 equals C (the cost). Equation: 2.60p=C
Hope this helps.
Answer:
(-6, -2)
radius = 5 units
Step-by-step explanation:
see attached for reference
recall that the general form for an equation of a circle looks something like:
x² + y² + Cx + Dy + E = 0, where
if (h,k) are the coordinates of the center of the circle,
h = - C/2 and k = -D/2
In our case, we are given:
x² + y² + 12x + 4y + 15 = 0
IF we compare this with the general equation above, we can see that
C = 12, D = 4 and E = 15
hence,
h = - C/2 = - (12/2) = -6
k = - D/2 = -4/2 = -2
Hence (h, k) = (-6, -2)
also, the radius is given by the equation
r² = (1/4)(C² + D²) - E
= (1/4)(12²+4²) - 15
= 40-15
= 25
r = ±√25
= ±5 (ignore negative because radius is always positive)
= 5
